Straw fermentation

Businesses around the world are searching for an alternative to corn silage as a substrate in the production of biogas. Straw, a by-product in the grain industry, offers itself as a good option here. Current state-of-the-art technology can use straw to obtain 50–70 percent of the gas yield otherwise produced by corn silage. Straw is therefore a real alternative for farms producing grain. Combined agricultural businesses that also rear livestock only need to make a few modifications to their workflows to exploit the significant advantages of straw fermentation. A greater use of straw as bedding in the stables and its downstream fermentation in a biogas plant may cut back on the significant costs for mechanical pulping processes. This presents a simple way of using straw as a substrate in the production of biogas.

Here, ENSPAR offers an energy-efficient straw pulping process to improve the fermentation capability of straw even further. A combined process of mechanical and biochemical pulping takes place before fermentation in the fermenter that significantly increases the biogas yield from straw. The process parameters in the preliminary stage are monitored constantly and can therefore be kept within the ideal operating range. The substrate is used to fuel the biogas plant once pre-treatment is complete. This is an energy-efficient way of using straw as a natural resource. Straw fermentation is ideal for combination with the fermentation of manure, chicken droppings or residue from the food industry and is therefore a good concept for biogas plants in agricultural regions.


Profitable recycling of residues

Tons of organic residues that release methane during decomposition are accumulated in agriculture, food production and wastewater treatment. This gas can contribute significantly to climate change if it is emitted unchecked into the atmosphere.

Wastewater technology

Prozessing of manure, digestate and industrial wastewater

The disposal of manure, digestate and industrial wastewater is expensive and laborious. In many regions there is a strong oversupply of liquid manure and digestate from biogas plants. Food-producing companies generate highly contaminated wastewater. What is needed, therefore, are sustainable solutions that facilitate the transport of residues and reduce nutrient surpluses. ENSPAR has developed a treatment solution for the processing of highly polluted waste water streams of liquid manure, digestate and industrial wastewater.

Concept processing plant

In the processing plant, solids are separated from the water in a multi-stage process. Depending on the requirements, the treatment is supplemented by classical sewage treatment plant technology with nitrification and denitrification or by the proven reverse osmosis process. What remains are solids in varying amounts of water and in reverse osmosis a liquid nutrient concentrate.

The reliable technology convinces users by a high technical plant availability. The system is modularly scalable and can be used economically from as little as 20,000 m³ per year.
